Hmm... looks like they are still not using the 18Gbps HDMI 2.0 Level A chip capable of 4K@60p at 4:4:4. :(

Warmest regards

There are two types of 4:4:4 which one are you referring to ?
What would you say is the difference between them ? And what matters to a TV ?

Chroma Subsampling

Chroma subsampling is a form of lossy video (or image) compression used to reduce the amount of bandwidth and storage required to transmit and store video. Videos are compressed by storing less color information than brightness information. This is done to exploit the human eye’s lower acuity for color differences than for brightness.

RGB 4:4:4

No compression is performed on the video. All computer GPUs output video in this format and a few professional video cameras can record in this format.

Y'CbCr 4:4:4

No compression is performed on the video. Most computer GPUs can output video in this format and a few professional video cameras can record in this format.

Y'CbCr 4:2:2

Lossy video compression is applied with color resolution being halved horizontally. A 4:2:2 video only needs two thirds of the bandwidth required by an uncompressed video. Most professional video cameras can record in this format.

Y'CbCr 4:2:0

Lossy video compression is applied with color resolution being halved horizontally and vertically. A 4:2:0 video only needs half of the bandwidth required by an uncompressed video. Most commercial video (Blu-Ray, DVD, Cable) is delivered in this format and most consumer camcorders record in this format.

Y'CbCr 4:0:0

Lossy video compression is applied with color information being completely discarded. A 4:0:0 video only needs one third of the bandwidth required by an uncompressed video. Since there is no color information in the video, the video is completely monochrome (black and white).


Also they used cheap MediaTek soc :

Either one. If it can't do YCbCr it's very unlikely to work with RGB.

And we should avoid all TVs that lack 4:4:4. Maybe other models from other companies will be able to offer no compression performed on the video.

At least 1080p models of 2014 were able to do 4:4:4 ? If yes then maybe we see 4:4:4 in 2015 1080p models.

In the PC/game modes, a lot do.

What 4:4:4 footage are you going to be feeding the TV?

I want something that can do 4:4:4 footage from all sources not just in PC/game modes. So i rather buy a 1080p that can do 4:4:4 from all in 2015 than a 4k that can't do it.

http://www.5dfilmmaking.com/tut_444.htm
https://www.youtube.com/watch?v=7JYZDnenaGc#t=280

Sources produced by : digital cinematography systems that are capable of recording full resolution color data (4:4:4) or raw sensor data.

Can the current BluRay content like movies, on bluray disks or on USB sticks or via HDMI use 4:4:4 ? What about digital streaming like netflix ?

PC Mode allows the PC to send RGB signal directly to TV, without processing on TV's end right ?

Most 1080 pc can, YCbCr 4:4:4 and RGB(RGB looks worse).

4k tvs can do 3840x2160 RGB 4:4:4, i think only 10bit panels, like ub8500.

I know what chroma subsampling is. What I'm asking you is this:

From where are you going to get this content? You realize that the consumer stuff you buy is in 4:2:0, right?

Quote
Can the current BluRay content like movies, on bluray disks

No.

or on USB sticks

Yes, if you have 4:4:4 encoded content.

or via HDMI use 4:4:4 ?

Yes, if you have 4:4:4 encoded content.
